SEO helps improve your website’s visibility in unpaid search engine rankings (also called organic results). If your website is placed higher in search engine results, you are more likely to receive increased traffic to your website. Knowledge of SEO will increase your traffic, thus bringing in readers and the potential to earn money through those readers.
If you want to be famous or reach a wide audience, you will have to choose something slightly broader and work hard to make the best content for that topic. A subtopic relating to fitness, finance, or relationship advice is likely to reach the most people. Consider specific but broadly applicable topics such as managing money in college, or a marriage counseling blog.
Make it easy for readers to browse – If you want more pageviews, you should make it as easy as possible for readers to read your other blog posts. You will want to make it easy for readers to find your blog homepage, categories, tags, search bar, and so on. Also, I recommend including links in every single one of your blog posts, so readers can easily find related topics.
